 Alan,I am not entering the technology age, at least not without kicking and screaming.  My friend is looking after it for me, and without him I could not do it.Hank

Hi All,Preliminary testing of my annealing oven are good so far.  I do not have the controller system in place yet, so I simply feed power to the elements and the circulation fan.  I placed identical objects in the oven and hit the power.  I found that the parts were different temperatures, but soon realized that was because I do not have a controller method.  I then tried a new approach-I hit the power again for for about ten minutes then turned off the elements but left the fan running.  After about 15 minutes I tested the parts inside and they wear almost identical in temperature.  I also tested the wall temperatures all over the oven and they were also extremely close to each other.  I am quite confident that I will have a good even anneal.  My engineer friend is also making a temperature tracking system to ensure the anneal is to PVHO spec.Hank
